I've said if numerous times and it's still true. The 4506 is still king when it comes to reliability and I feel sure the -1 is as well. they just don't get any better. I've had mine since 1990 and never intend selling/trading it for any other...even an HK45. It's the one pistol I've ever had that never caused a FTF, FTE, FTRTB issue with any ammo. I can't say that about the 4566TSW, 457 or even the 4516-1 I've had. It reigns king in my house.
